The objective of the project, conducted by the Environment Agency, is to provide, for various river reach types, generic seasonal flow and water level regime requirements for key life stages of freshwater fish species to advise and influence the management of flow regimes.

This is part of our Good Practice Guidance for Fish, produced by Vaughan Lewis, Steve Coates and Kerry Sims.
